Prove the idea
before you bet
the budget.
SisuMVP turns ideas into real, working MVPs in about a month — so you put them in front of real users, learn what actually has opportunity, and invest only in what proves itself. You own everything from day one.
Validate fast, then own it.
Test before you invest — four moves.
- 01Frame the real problem
- 02Build a working MVP
- 03Put it in front of real users
- 04You own it — then scale
An organisation has twenty ideas. The old way validates them one at a time.
Each idea takes months and serious money to build far enough to even know if it's worth pursuing. Most of that spend is wasted on ideas that turn out wrong — and the good ones surface far too late.
SisuMVP builds working MVPs for many ideas at once, on the order of a month. Real, usable prototypes you put in front of real users. You see which ideas have opportunity — and then decide where to invest.
- Build one idea fully before you learn anything
- Months of spend before the first real signal
- Good ideas surface late; bad ones cost the most
- Vendor lock-in on someone else's platform
- Working MVPs for many ideas, in about a month
- Real users, real signal — before the big budget
- Spend big only on what's already proven
- You own all code, data and infrastructure from day one
Deepest strength: AI applications over your own data.
RAG over your data
Grounded answers with citations — not hallucinations. Your documents become a source you can interrogate in plain language.
Hybrid search
Vector embeddings fused with keyword/full-text search for high recall in any language — with strong multilingual handling, including Finnish.
Agentic tool-use
LLM agents calling typed, safe tools — SQL templates, search, lookups — to assemble correct, auditable answers.
Chat-over-your-data
Streaming chat interfaces that let non-technical users question a whole corpus, with history and feedback built in.
Ingestion & crawling
Automated, self-healing pipelines that keep a corpus current and observable — even from messy public sources.
Programmatic data APIs
Turn a messy public or private source into a clean, billable JSON API with scoped keys and usage metering.
Fast, correct, and entirely yours.
Fast
Working software quickly — no long discovery-theatre phase. Sisu means we ship.
Correct
Grounded answers, citations, auditable behaviour. Hallucination and silent failure are bugs, not quirks.
Owned by you
Deployed on infrastructure you can take over. Source code, data and operations all handed over. No permanent dependency on us.
Pragmatic
Self-hosted where it makes sense for cost, residency and GDPR; managed cloud where it's faster. Chosen per project.
Finnish public sector
Municipalities, cities and agencies sitting on large archives of decisions and records that need to be searchable and answerable.
Finnish SMEs
Businesses that want AI working over their own documents, knowledge bases and operational data — without lock-in.
EU & international
The techniques are language- and border-agnostic. Other European municipalities and companies are a natural extension.
